2. determine whether each of these functions is o(x2). a) f (x) = 17x + 11 b) f (x) = x2 + 1000 c) f (x) = x log x d) f (x) = x4/2 e) f (x) = 2x f ) f (x) = x·x

it would be 6xy and -16xy.

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
